This contribution proposes a minimum bit error rate (MBER) decision feedback equaliser (DFE) designed for single-input multiple-output (SIMO) systems employing a quadrature phase shift keying (QPSK) modulation scheme. It is shown that this MBER design is superior over the standard minimum mean square error DFE in the SIMO scenario considered, in terms of the achievable system bit error rate. A ...
Cooperative communication systems, which make use of the intermediate relays between transmitter and receiver, have been employed as an effective technique to combat channel fading enhance system performance. systems some drawbacks such high latency may diversity order not guaranteed. To alleviate negative effects these factors, relay selection protocol is in cooperative increase overall Relay ...
3bit از مجموع 12 bit کل adc در طبق? این mdac تولید می شود و برای این منظور از سیستم 2.5bit استفاده شده است که 1bit از 3bit تولید شده صرف error correction می شود و بعد از جمع با بیت طبق? بعد 1bit تولید می کند به همین دلیل مانند 0.5bit عمل می کند. همچنین خطای گین محدود اپ امپ را با استفاده از تغییر نسبت خازن فیدبک به خازن واحد اصلاح می کنیم که در این روش درصدی برای تغییر گین حلقه باز اپ امپ به طو...
An atomic broadcast protocol is a very important building block of any fieldbus based dependable distributed embedded system. Under certain error scenarios native CAN mechanisms do not enforce atomic broadcast and inconsistent message duplicates or omissions may occur. The probability of those error scenarios depend on an important factor, the CAN bit error rate. However, up to our best knowled...
This paper deals with the modeling and the evaluation of a multiplicative phase noise influence on the bit error ratio in a general space communication system. Our research is focused on systems with multi-state phase shift keying modulation techniques and it turns out, that the phase noise significantly affects the bit error rate, especially for higher signal to noise ratios. These results com...
